This talk focuses on one of critical optimization provided as a part of the VC++ compiler: 'Profile Guided Optimization (PGO)'. PGO in simple words is somewhat a major component of the secret sauce for high performant Microsoft internal products (Windows, Internet Explorer, Lync, Office, Surface and many others). To summarize, PGO helps in improving the runtime performance of the application by training it for a set of common user scenarios. This talk will go over a brief description of this optimization, the improvements that we have made recently followed by an exercise and demo on how PGO can be performed to performance boost your native application.
